I have been yo-yo dieting for decades (over 3).
I have done loads of diets (lighter life, SW, WW, HFLC, 5:2, 16:8, FAST800, Cambridge) - I have lost 3st at least twice, 2 stone maybe 4 times, and a stone multiple times ..... I have never maintained any loss for more more than 6 months ...... always regained and over the decades my has weight has just got higher......all time personal best in Jan of 13st 7lb and I am only 5ft 3inches.
I haven’t heard of that book (I have read millions of diet books over the years) but I must be the cliche....anyone who has read it can you let me know if I am now just fucked metabolically?
We lose significant muscle mass each decade naturally through ageing and then rapidly hormonally through peri meno - less muscle means lower BMR - so if you eat and move the same you (even healthy foods) you gain weight - middle age spread.
So that’s going on whether you are already overweight or not.
Of course you can intercept this natural process by eating less, exercising more and specifically actively building more muscle so that BMR is increased.
But if you have done all the rapid weight loss programmes like I have - when you loss your “weight” if it is more than 2lb a week - then you are actually losing muscle ...... which of course is counterproductive .... less muscle means a lower BMR .... so we need even less calories.....
We need our bodies metabolism to be like a large engine performance car so that the same amount of calories are gobbled up in seconds rather than a 50cc engine which is overloaded and can’t burn them quickly enough.
So to increase BMR - I am looking to replace the muscle and metabolism lost to decades of silly diets and to age and menopause in general.
This is going to be my priority - so doing a whole body functional resistance / weights programme - which can shift metabolism in a few weeks.
I will also manage my eating as well - I have cut alcohol as this led to snacking and will keep 16:8 as this helps me as well.
I have joined SW (again) just for the weekly weigh in but I will not be looking for a round of a applause for loosing 3,4,5 lb in a week which I can easily do - I will be cross with myself if this happens again.
Also eating and digesting food is responsible for 10% of our BMR - so why would you cut this out. We need to eat a wide range and large volume of fruits and veg to give our gut a work out and burn off fat.
So OP - sorry that you are where you are - you are obviously much younger than me - would suggest that you work on raising your BMR by building muscle and eating more.
